What is the process for calculating and monitoring the personalized rate of return for my 401k account?

To calculate and monitor the personalized rate of return for your 401k account, you need to track the contributions you make, the performance of your investments, and any fees or expenses. You can use a formula to calculate your rate of return over a specific period, such as the time-weighted return method. Monitoring involves regularly checking your account balance, comparing it to your contributions, and assessing the overall performance of your investments.
